Field germination of alfalfa seed submitted for registrationin Colorado and varying in hard seed content
1940
Weihing, R.M.
The data show that samples of seed with 20 to 62% of hard seeds produced about equal numbers of plants in the field. These samples averaged 57 to 60% germination. Samples with less than 20% hard seeds averaged 61 to 64% germination, slightly higher germination than for samples containing 20% or more of hard seeds. Emergence was more rapid for samples of seed with few hard seeds than for those with many, but 2 to 3 weeks after planting all samples had nearly equal numbers of plants. The data indicate that under favorable field conditions not more than 70% emergence can be expected for samples of seed germinating nearly 100% in the laboratory. Alfalfa seed containing many hard seeds has almost the same agricultural value for planting as alfalfa seed containing few hard seeds.
